The Infineon CY7C0241-15AXCT is a 72Kbit dual-port asynchronous SRAM organized as 4K words by 18 bits. It provides two independent ports with separate address, data, and control lines, allowing simultaneous read/write access from two bus masters without external arbitration logic.
Buyers should plan for last-time-buy or lifetime-buy quantities if the program has remaining demand, as supply will only tighten over time.
Yes, the CY7C0241-15AXCT is listed as obsolete. Infineon has discontinued production. For legacy designs, the part is available through surplus and broker channels.
Asynchronous dual-port SRAM, like the CY7C0241-15AXCT, does not require a clock signal for read or write operations — access is controlled by chip enable, output enable, and write enable signals. Synchronous dual-port SRAM uses a clock to latch addresses and data, which can simplify timing closure in high-speed designs but adds clock distribution and setup/hold constraints. For a 15 ns access time part, asynchronous operation is straightforward to interface with most microcontrollers and FPGAs without a dedicated memory controller.
